Summary:
Historically seismic and other data have been stored on tape media of various types. The density of data on tape has increased over time. Access times have improved as well but they are not as fast as disk. Disk storage comes in various guises from cheap commodity to highly resilient. A cost benefit analysis shows that high speed intelligent disks are more cost effective than multiple cheap disks. Additional work has demonstrated that using Object storage on disk significantly improves access time to data as compared with standard Btree storage. The advent of cheap solid-state storage has changed the way we view storage and more and more systems are appearing with solid-state only storage (laptops, phones, tablets and high end analytics machines). Has the time now come to ditch tapes and disks and switch to solid state?
